1 From the Departments of Radiology (M.B., L.C., C.G., R.P.M.) and Urology (G. Savoca, G.L.), University of Trieste, Trieste, Italy, and the Department of Radiology, A.O. Santa Corona, Pietra Ligure, Italy (G. Serafini). Presented as an education exhibit at the 2003 RSNA Scientific Assembly. Received May 5, 2004; revision requested June 14 and received December 8; accepted December 13. All authors have no financial relationships to disclose.

A number of surgical procedures that significantly change the penile anatomy and vasculature can be used to manage pathologic conditions of the penis (eg, congenital and acquired deformities, erectile dysfunction, priapism). Phallic reconstruction surgery can be used for sex reassignment and after penile amputation or for correction of congenital malformations. Color Doppler ultrasonography (US) clearly depicts the normal penile anatomy and postoperative changes (eg, changes of the tunica albuginea, extraalbugineal pathologic fluid collections, cavernosal tissue changes produced by scars and fibrosis). It is also effective in evaluating surgery-related complications and determining the causes of erectile dysfunction and other unsatisfactory long-term results. Moreover, color Doppler US of the penile vessels and vascular anastomoses following revascularization allows direct evaluation of flow characteristics, shunt patency, and venous engorgement. Color Doppler US is the imaging modality of choice in evaluating patients who have undergone penile surgery.
